Tommy Dreiling asked for information on Nile Green to identify a piece of glass he had. Marshall Ketchum shared a description and jpg of a Nile Green piece. Tommy responds:
That’s it. My vase is shape 7188. I knew it was Steuben because the shape, size and spiral optic are an exact match to the line drawing but I didn’t know the color.

Ah–success. Next, Professor David Chadwick-Brown of San Diego has comments on the color Nile Green.
Alan, there is a putative Nile Green on the eBay Buy it Now (#7386l854l7) page. It looks like Gardner’s attribution of that color to a goblet on Plate XXII. Whereas Marshall’s has a blue hue, I find this more on the yellow side, though both computer and plate print reliability may be the ultimate determinant – nothing like seeing something in the flesh, so to speak.

I have a small goblet/martini glass with short twist stem in what I thought was Nile, or it was closer to that than any other. At Rande Bly’s prompting, I put it (and some other pieces) to black light test, and it glows, just as does Pomona. Now, unless we know that Nile also had some uranium, this may be just a dilute form of Pomona.

Black light also was put to a bowl and underplate, attributed to Steuben and with signature which I have always doubted, and there is definitely uranium present.

Keep up the conversations in color, for this is the kind of information we all can contribute to, and benefit from, and as always, Alan, thank you for orchestrating the Steuben symphony.

As David Chadwick-Brown comments, this sharing of information is helping with identification and confirmation of pieces of Mr. Carder’s works. From all of this dialogue we now have added to our knowledge, our web-page will be enhanced with yet more permanently posted color information, and finally, an idea. Ed Bush’s idea is to create a collection of glass that can be identified towards a goal of identifying the bulk of Mr. Carder’s 140 color creations to be placed in a museum setting for examination. Why not?

Finally, I would again note that this important subject of Mr. Carder’s colors will involve at least two sessions lead by Greg Merkel on this upcoming year’s Symposium (Oct. 2-3) at CMoG in Corning, NY.
